Description of the invention (6) However, in the case where the pixel size is reduced to obtain higher image quality in the liquid crystal device provided with fly-eye microlenses, the desired improvement graph cannot be obtained. Image, mainly due to the decrease in contrast. This is mainly due to the disorder of liquid crystal alignment in each pixel. In particular, in the conventional liquid crystal display device, due to the electric field between the pixel electrodes, a region where the liquid crystal alignment fails is called a v 'boundary line, which easily occurs between adjacent pixel electrodes. The "boundary line" is defined as the failure of area penetration or reflection caused by the failure of the area alignment of the liquid crystal occurring along the side of the pixel due to the side electric field acting between adjacent pixel electrodes. Regional liquid crystal alignment failure is typically caused by the liquid crystal molecules tilting in a direction different from the pre-tilt direction due to the electric field on each side. Incidentally, the above-mentioned J P-A 7-3 3 4 7 7 9 proposes to perform an alignment process (friction) in a direction parallel or perpendicular to the side of a rectangular pixel. The occurrence of this 'v boundary line' will not cause problems in conventional low-resolution liquid crystal devices, but when smaller-sized pixels are needed to meet better image quality including higher resolutions, the image will be caused Reduced quality. Description is made with reference to FIG. 2B, which indicates that the result of our analysis is an enlarged view of a pixel unit including three main color pixels between the color pixel arrangement patterns shown in FIG. 2A. FIG. 2B indicates that as a result of the friction in the direction of the dotted arrow of the lower substrate and the direction of the solid arrow on the upper substrate, a pre-tilt is formed in a direction of 45 degrees as shown by the dotted arrow of FIG. 2B.

Invention Description (7) 2 1 4 overlaps with the focal point 2 1 5 and causes a decrease in contrast. As a result, the image quality is reduced. To avoid being obstructed by the boundary line 2 1 4, it is necessary to reduce the spot size or enlarge each pixel size to reduce the effective mirror-to-hole ratio (that is, the area ratio of the hole 2 13 to the pixel electrode 2 1 2). This is the opposite of the requirement for higher resolution. On the other hand, if the reduction of the spot size is performed by cutting off a part of the light entering the pixel with the change of aberration, or it is difficult to reduce the size of the light source due to light limitation, the resulting image Will darken. In addition, in a conventional liquid crystal device provided with a fly-eye microlens (as disclosed in JP-A 8 — 1 1 4 7 8 0) described with reference to FIG. 25, the projection display image is enlarged by R on the screen.

Subsequently, the paper wave scale applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -34-514754 A7 B7 V. Description of the invention (32), the R light is projected as a part of the image light, which is the same as the above G light The method depends on the received light modulation and has a level level. (Please read the precautions on the back before filling this page.) Incidentally, Fig. 10 indicates a state where the G light and R light on the pixel electrodes 2 6 g and 2 6 r overlap each other, which causes disturbance to each other. However, this is only because the thickness of the liquid crystal layer 25 is graphically enlarged for easy understanding. The actual thickness of the liquid crystal layer 25 is about 5 // m, which is much smaller than 50 to 1 〇 // m of the sheet glass 23, so this interference does not actually occur regardless of the pixel size. FIG. 11 indicates a planar positional relationship between the fly-eye microlens 2 1 1 and a 10 # m square pixel electrode 2 1 2 in an embodiment. Unlike the second embodiment shown in Fig. 4B, the fly-eye microlens is designed to act on all R, G, and B color pixels. Therefore, the size of a (color) pixel must be relatively reduced so that the boundary line can occupy a larger area of the pixel electrode. In addition, in the case of an image showing the same illumination over the entire area, adjacent pixels of different colors are easily affected by the side electric field. Therefore, in this embodiment, a reduction in image quality due to a boundary line easily occurs, so that the present invention can exhibit greater effects. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, in particular, as shown in Figure 11, by allowing the optical axis 2 // m to be shifted in the X and y directions (that is, right and downward) Light spots to avoid the borderline. For example, in this example, it is assumed that a border line of 4 // m width occurs and the diameter of the spot is set to 6 // m. Fig. 11 indicates a state in which a light spot 2 1 5 is formed to avoid a boundary line 2 1 4. However, it has been experimentally confirmed that the shift of the optical axis leads to a significant improvement in image quality, such as contrast, even if some overlap with the boundary line at the edge of the light spot 2 1 5 occurs, compared with the paper standard, the Chinese national standard applies (CNS) A4 specification (21〇 < 297 mm) -35- 514754 A7 B7 V. Description of the invention (33) There is a known situation of optical axis shift. 1 2 A-1 2 C, the color analysis according to this embodiment will be described.

Between these, Fig. 12C indicates the cross section corresponding to Fig. 10 along the y-z plane, and points out the way in which G light and R light pass through the respective fly-eye microlenses. 2 2 It can be understood from FIG. 1C that each G pixel electrode 26 is placed directly below the center of the relevant fly-eye microlens 22, and each R pixel electrode 26 is placed in the relevant adjacent fly-eye micro Just below the boundary between the lenses 22. Therefore, it is preferable that the incident angle Θ of the R light is set to provide 値 η 0, which is equal to the pixel pitch (between the G pixel and the R pixel) and the distance between the fly-eye microlens and the pixel electrode ( For example, the ratio of 1 0 0 // m) is 値. On the other hand, FIG. 12B shows an X-y cross section of the liquid crystal panel 2. Along the X-y section, the B pixel electrode and the G pixel electrode are alternately arranged as similar to FIG. 12C. Thus, each G pixel electrode is disposed directly below the center of the relevant fly-eye microlens, and each B pixel electrode is disposed directly below the boundary between the relevant adjacent fly-eye microlenses. Incidentally, after the polarized light of the PBS 3 is illuminated by the PBS 3, the B light is incident on the liquid crystal panel in an oblique direction along the X-y plane, so that the B light incident through the fly-eye microlens is reflected by the B pixel electrode, And as shown in FIG. 12B, in the same manner as the R light, the fly-eye microlenses adjacent to the fly-eye microlenses incident in the X direction are emitted. The B light entering the B pixel electrode is modulated by the liquid crystal adjacent to the B pixel electrode, and the paper size is applied to the Chinese National Standard (CNS) A4 specification (210X 297 mm) when the paper size is emitted.

In the liquid crystal panel according to this embodiment, the color pixels of R, G, and B are arranged in the order of R G R G R G in the z direction, and are arranged in the order of B G B G B G in the X direction (as shown in FIG. 12A). Therefore, each pixel has a vertical size and a side size, which are respectively half of the size of the fly-eye microlenses, and the pixel pitch is half of the size of the fly-eye microlenses in the X and z directions, respectively. In addition, each pixel is disposed directly below the center of a two-dimensional related fly-eye microlens.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Now, pay attention to the G light used to illuminate the LCD panel. In this embodiment, G light is incident perpendicularly to the liquid crystal panel. Among the G-colored light, the G-colored light incident on a fly-eye microlens 2 2 a is represented by an arrow G (in) in FIG. 18. As shown in FIG. 18, the G light is collected by the fly-eye microlens 2 2a after passing through the liquid crystal layer 2 2 5 to illuminate the G pixel electrode 2 2 6 g, and then passes through the fly-eye micro-lens on the other TFT side substrate. The lenses 22, a are emitted from the liquid crystal panel. Although the deflected G light passes through the liquid crystal layer 2 2 5 in this manner, the liquid crystal 2 2 5 driven by the electric field formed between the pixel electrode 2 2 6 g supplied with the data voltage and the counter electrode 2 4 is optically modulated, However, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) '--- -41-514754 A7 B7 V.

Depending on the degree of modulation received at this stage, the change allows the quality of the G light to pass directly through the polarizer 47 to the projection lens 1, thereby expressing the density order at the pixel 2 2 6 g. Then, note the R light incident on the liquid crystal panel in the oblique direction in the section (y-2 plane) shown in FIG. 18. For example, the R light represented by the arrow R (in) incident on the panel is first polarized by the polarizer 46, and then condensed by the fly-eye microlens 2 2b to illuminate the R pixel electrode 2 2 6 r. The left position of the fly-eye microlens 2 2 b is shifted upward, and after passing through the R pixel electrode 2 2 6 r, it is also emitted from the panel through the fly-eye microlens 2 2 6 > a as if by G / R ( Out). During passing through the liquid crystal layer 2 2 5, the deflected R light is also modulated to a certain extent, depending on the formation between the R pixel electrode 2 2 6 r supplying the data voltage and the opposite electrode 2 4 and applying to the liquid crystal 2 2 5 Depending on the electric field. The R light thus emitted from the liquid crystal panel is projected as part of the pixel light in the same manner as the G light. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Figure 18 indicates a state where G light and R light adjacent to the G pixel electrode 2 2 6 g and the R pixel electrode 2 2 6 r overlap each other, and thus interfere with each other. However, this is only because the thickness of the liquid crystal layer 2 2 5 is graphically enlarged for easy understanding. The actual thickness of the liquid crystal layer 2 2 5 is about 5 A m, which is much smaller than 50 to 100 // m of the sheet glass 23 and 23>, so this interference does not actually occur regardless of the size of the pixel.
